In Depth

       Although around eight to ten meters long in life,‭ ‬Lirainosaurus was still pretty small for a titanosaur.‭ ‬However,‭ ‬while the fossils of several individuals have been found,‭ ‬and from most parts of the skeleton,‭ ‬these remains are usually very fragmentary.‭ ‬The fossils that are known indicate that Lirainosaurus was a fairly gracile‭ (‬lightly built‭) ‬titanosaur,‭ ‬and was possibly related to other genera such as Saltasaurus.‭ ‬This interpretation is supported by the discovery of osteoderm armour associated with Lirainosaurus remains.‭ ‬In life these osteoderms would have been plates of bone that lay just below the outer surface of skin to provide some defence from attack.‭
